Which Oracle database to use in a 64 bit laptop to make a JDBC connection.

I have to work on Eclipse and make a Billing System. They have asked me to use a Oracle DB and Tomcat.

The problem i am facing is my laptop is 64 bit. I found Exlipsee IDE JEE for 64 bit . But i cant find the right database or tomcat apache. I installed Oracle 11g ExpressEdition(only Windows 32 bit is available on their website) but when i create a table in it. I cant access it while making the jdbc connection when i do so by going in the Device manager and so on. I can see something called SQL Native Client and Microsoft Access and so on. It says driver doesnt exists and architecture not supported.

I have 4 weeks left to complet this project! And i havent started at all! Please help me in finding the right versions which will work!

Above mentioned are the techincal specifications required for my project. In the Model Layer of MVC architecture they have said Pl/SQL . I need a Database compatible with my 64 bit laptop. Also are there any jdbc drivers that i need to install? Please Suggest Something. I would be very grateful to all.

you should have an Oracle JDBC driver in your libraries in Eclipse. Check which version it is and make sure it is the correct one.

The reports are mixed on using the 32 bit version of Oracle Express on 64 bit windows. If you can't get Oracle to work, you can use a different database for development.

Your application should be loosely coupled with the database anyway so that it won't matter which one you use while you develop. Get HSQLDB, MySQL, or Postgresql and develop against that until they give you an oracle DEV environment on their servers to deploy against.
